Ready to Learn DevOps? Lesson 0: Start Here CHAPTER 2 DevOps BootCamp: Fall 2018 DevOps BootCamp is a single-day event with one track to help attendees kick off the year with fundamentals of system administration and software development. The hands-on workshop is designed to teach participants DevOps, a program development process that includes building, testing, and releasing software. Please register if you’re planning on attending BootCamp this fall. 5 OSU DevOps BootCamp Documentation, Release 0.0.1 6 Chapter 2. DevOps BootCamp: Fall 2018 CHAPTER 3 DevOps Open Office Labs Following the Fall Kickoff, we will be hosting bi-weekly open office labs in Milne 224 in two hour blocks. These labs initially will be structured around the content on the website but will aim to be mostly hands on. OSL students and staff will be on-site to help you work through the content. Content discussed at each lab will depend on the attendees interest. We will also be opening up our Milne server room for students to learn and interact with actual hardware. Some interesting topics we may end up discussing include (expanded on the lessons we already have on the website): • Automated Linux installs • Network switch configuration • Out of Band (IPMI) configuration and usage • Installing servers in racks and configuring them • Setting up servers to run various services (email, web, DNS, etc) • Open Source software contributions Our Milne server room includes three OpenCompute Racks donated from Facebook (includes a total of 90 compute nodes), managed network switches, and other various rack mounted server hardware. 7 OSU DevOps BootCamp Documentation, Release 0.0.1 8 Chapter 3. DevOps Open Office Labs CHAPTER 4 Schedule The DevOps BootCamp content is available for free but meet-space guided lectures are offered throughout the year. Check the schedule below for our in-person lectures; each lecture covers a different part of the curriculum covering the entire course during the OSU academic school year.

Donate OSU DevOps BootCamp Documentation, Release 0.0.1 • Sometimes intermixed with Systems Administrators who want Engineer in their title Definition: DevOps Engineers • Newer position • Mix of Systems (Operations) and Development work • Involved where the application and its platform meet • Responsibilities include a mix of both Ops and Dev, usually: – General infrastructure/automation – Continuous Integration and Testing – Developer Environments/Workflow – Logging – Often on-call Definition: Site Reliability Engineers (SRE) • SRE and DevOps Engineers share the same foundational principles • SRE is viewed as a “specific implementation of DevOps with some idiosyncratic extensions” • SRE was originally created at Google as a process to improve managing their services • Most large tech companies now follow SRE processes DevOps DevOps is a field which takes skills from Software Development and Operations Engineering to create and run applications more effectively. TLDR: Development + Operations == Better Services DevOps defines 5 key pillars of success: 1. Reduce organizational silos 2. Accept failure as normal 3. Implement gradual changes 4. Leverage tooling and automation 5. Measure everything What DevOps BootCamp (DOBC) is TLDR: Couch to DevOps in 1 school year DOBC is a free education program offering: • Mentors teaching DevOps related tools and concepts. • A challenge for anybody willing to put in the effort. • One-on-one Apprenticeship. 5.1. Lesson 0: Start Here 13 OSU DevOps BootCamp Documentation, Release 0.0.1 • Hands-on training and lectures • Free and Open Source course materials! What DOBC is not DevOps BootCamp is not: • A for-credit OSU class • A Student job • Easy Why DOBC Exists DOBC was created because the OSU OSL: 1. Merged with the school of EECS. 2. Wanted to help students meet Company demands and expectations of recent graduates. 3. Needed to bridge the “Skills Gap” of the OSU EECS curriculum. 4. Wanted to build a DevOps Learning community. What You Will do You will Learn: • Linux systems • Networking • Software development • Tools and why they matter You will build: • Functioning applications on the cloud • Cloud infrastructures Who Teaches DOBC The teachers of DOBC include: • OSL Students • OSL Faculty • Guests from The Industry • You! 14 Chapter 5.
